Okay, I've got the structure done, I know how the sugar-phosphate back-bone works, but I need to specify the base pairs. I know that Thymine goes with Adenine and Guanine goes with Cytosine but is there a specific order they go from the bottom to the top, along the sugar-phosphate back bone? Or is it unique in every double helix and that's what makes the different genes, hence different characteristics in an organism?

In our schools, it is the only option allowed to be taught concerning the creation (which, coincidentally, has nothing to do which Darwin's theory), however improbable the other theories may be. And, from what it seems, it is the only thing the general population considers to be truth in this field. This being the case, why do we still call it a theory?

I would appreciate it if you had substancial proof to back up your argument. Thank you.

In a particular species of rodent, there is one gene, B/b with incomplete dominance, that determines fur color.

Suppose that in a parent (P1) population of this rodent, you find

384 black individuals (BB)
123 gray individuals (Bb)
24 white individuals (bb)

a) What are the genotype frequencies in the P1 population?
b) What are the allele frequencies in the P1 population?
c) Assuming Hardy-Weinberg Equilibrium, what percent of the offspring population (F1) will have gray fur?

Explain, in words, how you calculated the answer for (c).
